293 | =head1 DESCRIPTION |
294 | |
046ad905 |
295 | This class represents the connection to an RDBMS via L<DBI>. See |
296 | L<DBIx::Class::Storage> for general information. This pod only |
297 | documents DBI-specific methods and behaviors. |

315 | =head2 connect_info |
316 | |
bb4f246d |
317 | The arguments of C<connect_info> are always a single array reference. |
1b45b01e |
318 | |
bb4f246d |
319 | This is normally accessed via L<DBIx::Class::Schema/connection>, which |
320 | encapsulates its argument list in an arrayref before calling |
321 | C<connect_info> here. |
1b45b01e |
322 | |
bb4f246d |
323 | The arrayref can either contain the same set of arguments one would |
324 | normally pass to L<DBI/connect>, or a lone code reference which returns |
325 | a connected database handle. |
d7c4c15c |
326 | |
2cc3a7be |
327 | In either case, if the final argument in your connect_info happens |
328 | to be a hashref, C<connect_info> will look there for several |
329 | connection-specific options: |
330 | |
331 | =over 4 |
332 | |
333 | =item on_connect_do |
334 | |
335 | This can be set to an arrayref of literal sql statements, which will |
336 | be executed immediately after making the connection to the database |
337 | every time we [re-]connect. |
338 | |
339 | =item limit_dialect |
340 | |
341 | Sets the limit dialect. This is useful for JDBC-bridge among others |
342 | where the remote SQL-dialect cannot be determined by the name of the |
343 | driver alone. |
344 | |
345 | =item quote_char |
d7c4c15c |
346 | |
2cc3a7be |
347 | Specifies what characters to use to quote table and column names. If |
348 | you use this you will want to specify L<name_sep> as well. |
349 | |
350 | quote_char expects either a single character, in which case is it is placed |
351 | on either side of the table/column, or an arrayref of length 2 in which case the |
352 | table/column name is placed between the elements. |
353 | |
354 | For example under MySQL you'd use C<quote_char =E<gt> '`'>, and user SQL Server you'd |
355 | use C<quote_char =E<gt> [qw/[ ]/]>. |
356 | |
357 | =item name_sep |
358 | |
359 | This only needs to be used in conjunction with L<quote_char>, and is used to |
360 | specify the charecter that seperates elements (schemas, tables, columns) from |
361 | each other. In most cases this is simply a C<.>. |
362 | |
363 | =back |
364 | |
365 | These options can be mixed in with your other L<DBI> connection attributes, |
366 | or placed in a seperate hashref after all other normal L<DBI> connection |
367 | arguments. |
368 | |
369 | Every time C<connect_info> is invoked, any previous settings for |
370 | these options will be cleared before setting the new ones, regardless of |
371 | whether any options are specified in the new C<connect_info>. |
372 | |
f5de3933 |
373 | Important note: DBIC expects the returned database handle provided by |
374 | a subref argument to have RaiseError set on it. If it doesn't, things |
375 | might not work very well, YMMV. If you don't use a subref, DBIC will |
376 | force this setting for you anyways. Setting HandleError to anything |
377 | other than simple exception object wrapper might cause problems too. |
378 | |

046ad905 |
457 | Arguments: $subref, @extra_coderef_args? |
458 | |
d4f16b21 |
459 | Execute the given subref using the new exception-based connection management. |
046ad905 |
460 | |
d4f16b21 |
461 | The first two arguments will be the storage object that C<dbh_do> was called |
462 | on and a database handle to use. Any additional arguments will be passed |
463 | verbatim to the called subref as arguments 2 and onwards. |
464 | |
465 | Using this (instead of $self->_dbh or $self->dbh) ensures correct |
466 | exception handling and reconnection (or failover in future subclasses). |
467 | |
468 | Your subref should have no side-effects outside of the database, as |
469 | there is the potential for your subref to be partially double-executed |
470 | if the database connection was stale/dysfunctional. |
